This batch renaming tool processes images entirely in your browser. Perfect for photographers organizing shoots, digital asset managers maintaining collections, and anyone needing consistent file naming across multiple images.

Step-by-Step Guide: How to Batch Rename Images

Step 1: Upload Your Images

Click "Select Images" or drag and drop multiple image files onto the upload area. The tool accepts JPG, PNG, and WebP formats.

Upload multiple files:

• Click "Select Images" button
• Hold Ctrl (Windows) or Cmd (Mac) to select multiple files
• Or select all files in folder
• Or drag and drop entire folder contents
• Upload 2-1000+ images at once

Best for batch renaming:

• Event photography collections
• Product photo batches
• Stock photography sets
• Client deliveries
• Social media content
• Digital archives

Your uploaded files appear in the preview list showing current names. The file count displays total images ready for renaming.

Step 2: Choose Naming Pattern

Select one of four naming patterns to structure your new filenames.

Custom Name Pattern:

• Base name + sequential numbers
• Example: photo_001, photo_002, photo_003
• Most flexible option
• Ideal for: General organization, event photos, any custom naming

Date Pattern:

• Date + sequential numbers
• Example: 2026-01-08_001, 2026-01-08_002
• Uses current date or customizable format
• Ideal for: Daily shoots, time-organized archives, chronological filing

Sequential Pattern:

• Simple base name + numbers
• Similar to Custom Name
• Streamlined option
• Ideal for: Quick numbering, simple organization

Keep Original Pattern:

• Preserves original filenames
• Applies case changes or timestamps only
• No renaming structure applied
• Ideal for: Case standardization, adding timestamps without changing names

Click any pattern button to activate it. The preview updates instantly showing new names with selected pattern.

Step 3: Customize Base Name (Custom/Sequential)

For Custom Name or Sequential patterns, set the base name prefix for all files.

Base Name field:

• Enter custom text prefix
• Default: "photo"
• Examples: "wedding", "product", "event", "vacation", "client-name"
• Appears before number in filename

Base name tips:

• Use descriptive names for easy identification
• Keep names short but meaningful
• Avoid special characters (use letters, numbers, hyphens, underscores)
• Consider project or client names
• Use consistent naming across projects

Base name + number creates complete filename: "wedding_001", "product_042", "vacation_137"

Step 4: Set Numbering Options

Configure sequential numbering for your renamed files.

Start Number:

• First number in sequence
• Default: 1
• Examples: Start at 1, 100, 1000
• Use 0 for zero-based indexing
• Continue numbering from previous batches

Number Padding:

• Leading zeros for consistent length
• Default: 3 digits (001, 002, 003)
• Options: 1-6 digits
• 1 digit: 1, 2, 3, 4...
• 2 digits: 01, 02, 03, 04...
• 3 digits: 001, 002, 003, 004...
• 4 digits: 0001, 0002, 0003, 0004...

Padding tips:

• Use 3 digits for up to 999 files
• Use 4 digits for up to 9,999 files
• Padding ensures proper alphabetical sorting
• More padding = future-proof numbering

Proper padding prevents sorting issues where "10" appears before "2" in file lists.

Step 5: Customize Date Format (Date Pattern)

For Date pattern, specify how dates appear in filenames.

Date Pattern field:

• Default: YYYY-MM-DD (2026-01-08)
• Customize order and separators
• Available tokens:
  • YYYY = 4-digit year (2026)
  • MM = 2-digit month (01-12)
  • DD = 2-digit day (01-31)
  • HH = 2-digit hour (00-23)
  • mm = 2-digit minute (00-59)
  • ss = 2-digit second (00-59)

Date format examples:

• YYYY-MM-DD = 2026-01-08
• DD-MM-YYYY = 08-01-2026
• YYYY_MM_DD = 2026_01_08
• YYYYMMDD = 20260108
• YYYY-MM-DD_HH-mm = 2026-01-08_14-30

Date naming tips:

• YYYY-MM-DD format sorts chronologically
• Include time for multiple daily shoots
• Use underscores or hyphens as separators
• Avoid slashes (incompatible in filenames)

Date naming creates time-organized file collections automatically.

Step 6: Configure Additional Options

Two checkbox options provide extra naming flexibility.

Add Timestamp:

• Appends Unix timestamp to filename
• Example: photo_001_1704723456
• Ensures absolute uniqueness
• Prevents duplicate names
• Use when: Combining photos from multiple sources, ensuring unique names, preventing overwrites

Preserve File Extension:

• Keeps original file extensions (.jpg, .png, etc.)
• Checked by default
• Recommended: Leave enabled
• Unchecking removes extensions (creates files without extensions)

Keep "Preserve File Extension" enabled unless you have specific reason to remove extensions.

Step 7: Select Text Case

Choose how text appears in renamed files.

Original Case:

• Keeps entered capitalization
• "Photo" stays "Photo"
• "vacation" stays "vacation"
• Default option

lowercase:

• Converts all text to lowercase
• "Photo" becomes "photo"
• "VACATION" becomes "vacation"
• Consistent lowercase naming

UPPERCASE:

• Converts all text to uppercase
• "Photo" becomes "PHOTO"
• "vacation" becomes "VACATION"
• Consistent uppercase naming

Text case tips:

• Lowercase most common for file organization
• UPPERCASE useful for special projects or emphasis
• Original maintains your exact input
• Choose based on personal or organizational standards

Text case applies to base name and any custom text, not to file extensions.

Step 8: Preview New Names

Review the side-by-side comparison of current names versus new names.

Preview display:

• Left column: Current filenames
• Right column: New filenames
• Scrollable list for many files
• Updates live as you adjust settings
• File count shows total images

What to check:

• Naming pattern correct
• Numbers sequential and padded properly
• Base name spelled correctly
• File extensions preserved
• No naming conflicts or issues

Carefully review preview before downloading to ensure names meet your needs. Adjust settings and watch preview update instantly.

Step 9: Adjust Settings if Needed

Modify any settings to perfect your naming scheme.

Common adjustments:

• Change base name for better description
• Increase padding for larger collections
• Switch naming pattern for different organization
• Toggle timestamp for uniqueness
• Change text case for consistency

All changes reflect immediately in preview. Experiment with different configurations until names appear exactly as desired.

Step 10: Download Renamed Files

Click "⬇️ Download Renamed Files" to save all images with new names.

Download details:

• Format: ZIP archive
• Filename: renamed-images-[timestamp].zip
• Contains: All uploaded images with new names
• File size: Sum of all original images
• Download time: Varies by collection size

After download:

1. Locate ZIP file in downloads folder
2. Extract ZIP archive
3. Access renamed image files
4. Use renamed files in projects
5. Delete original files if desired

Using renamed files:

• Upload to cloud storage
• Import to photo management software
• Deliver to clients
• Archive in organized folders
• Post to websites or portfolios

The tool creates ZIP archive because browsers cannot download multiple individual files simultaneously. Extract ZIP to access all renamed images.

Batch Renaming Tips and Best Practices

Choosing Naming Patterns

Custom Name for most projects: Descriptive base name + numbers works universally. "wedding-smith_001" clearly identifies project and sequence. Use for client work, events, and general organization.

Date for time-based organization: Date-based naming automatically creates chronological order. Perfect for daily shoots, ongoing projects, or time-sensitive work. YYYY-MM-DD format ensures proper sorting.

Sequential for simple numbering: Basic numbering without descriptive names. Use when files already in proper folder structure or when minimal naming sufficient. Quickest option for basic organization.

Keep Original when renaming not needed: Preserve existing names while standardizing text case or adding timestamps. Use when current names acceptable but need minor modifications.

Number Padding Strategy

Match padding to collection size: Small collections (under 100) work with 2-digit padding. Medium collections (100-999) need 3-digit padding. Large collections (1000+) require 4+ digit padding.

Future-proof with extra padding: If collection might grow, use more padding than currently needed. Adding images later with different padding creates sorting problems.

Consistent padding across projects: Use same padding scheme for similar project types. Consistency simplifies file management and organization across multiple projects.

Base Name Best Practices

Be descriptive but concise: "wedding-jones-ceremony" better than "photo" or "wedding-john-jones-ceremony-main-church-december". Balance description with brevity.

Use clear separators: Hyphens and underscores separate words clearly. Avoid spaces (many systems replace with underscores anyway). "product-shoes" clearer than "productshoes".

Include project identifiers: Client names, project codes, or event identifiers make files instantly recognizable. "client-ABC-product" clearly identifies ownership and purpose.

Avoid special characters: Stick to letters, numbers, hyphens, and underscores. Other characters cause problems across different operating systems and software.

Consider sorting: If alphabetical sorting important, design base names accordingly. Prefix with dates or codes for specific sort order.

Organizing Large Collections

Batch rename by category first: Don't rename entire shoot in one batch. Separate ceremony, reception, portraits, etc. Rename each category with distinct base names: "ceremony_001", "reception_001", "portraits_001".

Use folders plus renaming: Combine folder organization with batch renaming. Create folders by category, then rename files within each folder. Folder + filename provides full organization.

Number in logical sequence: Start numbering at meaningful points. Main photos start at 001, alternates at 500, bonus content at 1000. Gaps allow insertions without disruption.

Maintain metadata separately: Batch renaming only affects filenames. Use photo management software to preserve EXIF data, keywords, and other metadata alongside file renaming.

Keep backup of originals: Before renaming important collections, backup original files with original names. Mistakes happen - backups provide recovery option.

Batch Renaming Use Cases

Event Photography

Wedding photography: Organize thousands of wedding photos efficiently. Rename ceremony photos as "wedding-smith-ceremony_001", reception as "wedding-smith-reception_001", portraits as "wedding-smith-portraits_001". Delivered collections professional and organized.

Corporate events: Rename conference, meeting, or party photos with event name and sequence. "conference-2026-day1_001" clearly identifies event and timing. Easy for clients to navigate and use.

Sports photography: Batch rename game photos with team names, dates, and sequences. "soccer-teamA-vs-teamB-2026-01-08_001" provides complete context in filename. Useful for athletes buying photos.

Birthday parties: Rename party photos with child's name and sequence. "birthday-emma-5th_001" makes sharing and printing simple for parents.

Product Photography

E-commerce catalogs: Rename product photos with SKU or product codes. "product-SKU12345-front_001" matches inventory systems. Consistent naming simplifies catalog management and website uploads.

Multi-angle products: Rename angles systematically: "product-123-front_001", "product-123-side_001", "product-123-detail_001". Clear angle identification in filename.

Product variations: Rename color or size variations distinctly. "shirt-blue-small_001", "shirt-red-large_001". Filename indicates product attributes clearly.

Before/after shots: Name transformation photos sequentially. "renovation-kitchen-before_001", "renovation-kitchen-after_001". Clear progression in filenames.

Stock Photography

Keyword-based naming: Rename stock photos with primary keywords. "sunset-beach-ocean_001" makes photos searchable and descriptive. Stock platforms benefit from descriptive filenames.

Category organization: Batch rename by category before upload. "nature-landscapes_001", "business-office_001", "food-desserts_001". Category in filename aids organization.

Model release tracking: Include model identifiers in filenames. "portrait-modelA_001" links photos to release documentation. Critical for commercial stock photography.

Seasonal collections: Date or season in filename. "christmas-2025_001", "summer-beach_001". Helps manage and update seasonal content.

Digital Asset Management

Client deliveries: Rename deliverable files with client name and project code. "client-acme-project-001_001" clearly identifies ownership. Professional presentation for client work.

Archive organization: Date-based naming for long-term archives. "YYYY-MM-DD_projectname_001" sorts chronologically and includes project identifier. Essential for multi-year archives.

Team collaboration: Consistent naming across team members. Everyone uses "project-code-category_001" format. Shared naming conventions prevent confusion and facilitate teamwork.

Version control: Number sequences track versions. "design-v1_001", "design-v2_001", "design-final_001". Clear version progression in filenames.

Personal Photo Organization

Vacation photos: Rename trip photos with location and date. "vacation-hawaii-2026_001" clearly identifies trip. Easy to find years later.

Family events: Name family gathering photos with event and year. "thanksgiving-2025_001", "reunion-smith-family-2026_001". Family archives stay organized.

Pet photos: Batch rename pet photos with pet name. "dog-max-2026_001" creates organized pet photo collection. Helpful for multi-pet households.

Hobby documentation: Rename project photos with project name. "woodworking-table-build_001" documents progress. Useful for portfolios or tutorials.

Frequently Asked Questions (FAQs)

Q: How many images can I rename at once?

A: The tool handles hundreds or even thousands of images simultaneously. Browser memory is the only limitation - most modern browsers comfortably process 500-1000 images. For extremely large collections (5000+), consider splitting into smaller batches for stability.

Q: Are my original files modified?

A: No! Your original files remain completely unchanged. The tool creates renamed copies in the ZIP download. Original files on your computer stay exactly as they were. You're always safe to experiment with different naming patterns.

Q: Can I undo renaming after downloading?

A: No built-in undo, but you still have your original files unchanged. If renamed files don't work out, simply discard the ZIP and re-upload originals with different settings. Always keep originals until confirming renamed versions are correct.

Q: What if two files get the same name?

A: The sequential numbering ensures each file gets a unique number, preventing name conflicts. Even if base name and date are identical, the incrementing number makes each filename unique. The tool automatically prevents duplicates.

Q: Can I add custom text between name and number?

A: Currently, the tool uses underscore separator between name and number (photo_001). For different separators or formatting, include them in the base name field: "photo-" creates "photo-001", "photo_img_" creates "photo_img_001".

Q: Why do I get a ZIP file instead of individual files?

A: Web browsers cannot download multiple individual files automatically due to security restrictions. ZIP archives bundle all files into single download. Simply extract the ZIP to access your renamed image files.

Q: Does the tool rename files on my computer?

A: No. The tool creates renamed copies in the ZIP download. Your original files on your computer remain unchanged. After extracting renamed files from ZIP, you can delete originals if desired.

Q: Can I preserve some original names?

A: Use "Keep Original" pattern to preserve original filenames while applying case changes or timestamps. For partial preservation, manually select and batch rename only specific files rather than entire collection.

Q: What happens to EXIF data and metadata?

A: All EXIF data, metadata, and image properties are preserved. Only the filename changes - the image file itself is identical to the original with all camera information, date taken, location, etc. intact.

Q: Can I use spaces in file names?

A: Yes, but not recommended. Spaces in filenames cause problems in many systems and command-line tools. Use hyphens or underscores instead. The tool doesn't prevent spaces but following conventions avoids future headaches.

Q: How do I rename files already on my computer?

A: Upload the files to this tool, apply new naming pattern, download renamed ZIP, extract files, and replace originals with renamed versions. Alternatively, use your operating system's built-in batch rename features for files already organized locally.

Q: Is there a file size limit?

A: No specific file size limit, but very large files (50MB+ each) may slow processing. The tool handles typical photo sizes (5-20MB) easily. Total collection size affects ZIP creation time - larger collections take longer to compress.

Q: Are my photos stored on any server?

A: No! All renaming happens entirely in your browser. Photos never upload to any server, aren't stored anywhere, and never leave your device. Complete privacy guaranteed for all photo collections.
